souri, have invented a new and useful Sash-Lock, ofV

which the following is a specification.

This invention relatesl'to a sash lock adapted for use' in `connectionwith windows, with or. without counter-balance weights for the sashes,wherebythesashes `can be locked either closed, or opened partially 4forthe purpose of ventilation, without danger of their'gbeing -opened fromthe outside by unauthorised persons.

The invention has for one of its objects to provide a sash lock which isof simple and inexpensive constmction, easy to apply to ordinarywindows, and reliable for holding a sash in any desired position.

A further object of the invention is the provision of a device .of thischaracter, which comprises two parts, and, which serves as a grip orhand-hold for assisting in raising or lowering the sash.v A

With these objects in view, and others, as will appear as the natureoithe invention is better understood, theA invention comprises thevarious novel features of construction and arrangement o f parts, whichwill be more fully described hereinafter, and set forth with.particularity in the claims appended hereto.

.- ln the accompanying drawing, which illustrates cerof'fthe embodimentsof the invention, Figure lis a fragmentary perspective view of a Windowshowing in' its unlocked positionby dotted lines. Fig. 3 is av sideelevation, partly broken away, of a modified form of sash lock. Fig. 4is a perspective view of a'mpdified form of gripping member.

Corresponding parts in the several figures are indicated throughout bysimilarcharacters of reference.

Referring tothe drawing, 1 designates the lower sash and 2 the frame ofa window to whichy the ,locking device is applied. The locking devicecomprises a straight,-

smooth-rod 3, suitably fastened at its ends, and a lock- Aing member 4.The rod 3 may be attached to thrn window frame 2 and the locking member4 to the sash, as

extending eye 5 for securing to the-sill of the window frame by means ofa screw 6, or equivalent means. The upper end of the rod 3 is held in abracket 7 which comprises a plate presented to the stile of the windowframe and secured thereto by screws 8. vOne `end of the plate is turnedlaterally in a. horizontalplane toform a lug 9 having a central aperture10 in which the upper end of the rod 3 is held. The rod 3 lmay thus beof any length and the bracket 7 can be arranged at any desired`point, soas to accommodate the sash lock to sashes Specification of LettersPatent. gippnmion nea october11,`19o6. serial sessanta.

venting children from opening thewindows far enough v to fall out.Another manner of securing the upper end of the rod 3 is shown in Fig.3, wherein the extremity of the rod is formed into an eye 11 forreceiving a screw, or equivalent `means, 12', whereby the said eye issecurely fastened tothe stile of the window frame. l

The locking member 4 comprises, preferably, though not necessarily, asingle piecefstructureV having abase 13 and two forwardly projectingportions 14 forming gripping jaws. ',lhe base 13 is presented to theinner face or front 'of the side rail of the window and secured theretoby screws 15 extending through apertures in lthe base 13 and screwingintothe said side-rail. The jaws or members 140i the locking device 4are diverged from the base 13. and are normally under a tension thattends to spread them apart. Each jaw 14 is provided with an aperture 16through which the rod 3 extends. The edges of the aperture 16 at thepoint 17 bite the v rod 3 and prevent relative movement between ,thesaid rod 'and the locking` device 4. The strip of metal from soA whichthe locking device 4 is made is of suitable spring.

material and the jaws14 are under considerable tension which tends tomhve them farther apart so that they will grip the rod 3. \The ends ofthe jaws opposite from the base 13 are bent inwardly toward each otherat 18, andV these inwardly bentportions 'are themselves bent forwardlyand outwardly inthe general direction of the jaws and form nger piecesor holds whereby the jaws can be gripped between the thumb and firstringer and compressed toward each other, so as to release the bitingedges 17 of the jaws fromthe rod 3 when it is desired to move the sash.In Fig. 2, the full line posi.

tion of the jaws or members 14 represents the device 4 locked withrespect tothe rod 3, while the dotted line position represents thedevice unlocked. It will be noted that in the dotted line position, thelinger-holds 19 are in contact and thus they serve as stops forpreventing the jaws from being compressed to such an extent as to biteon the rod 3 and thus prevent the sash from moving. When it is desiredto adjust the position of the sash, the finger-holds 19 are takenbetween the thumb and. r'st finger of' the left hand and the jaws movedto the dotted line position shown in Fig. 2.

IWhile the device 4 is held-in this manner, the handhold 20 on the sashis'gripped -in the right hand and then the sash can be raised or loweredby liftingup with both hands or pushing down, as the case may be.

v While the jaws are held in the dot-ted line position, the

device 4 serves as a hand-ho1d sirnilarto the handhold 20 to assist inraising or lowering 'the sash.

In Fig. 3, the locking device is composed of two parts,

l 20 and 2l whichare oi substantially the same construction and arrangedone within the other and secured by the same screws to the window sash.rlhis construction is employed where a strong gripping effect isdesired, the relatively thin member 21 serving as an auxv iliarygripping device and to reinforce theiouter memof sheet spring metal, butthe said device can be made from spring wire, if desired, as, forinstance, as shown in Fig. 4. In this construction, a single piece ofWire of suitable length is employedand it is shaped at its middle toform the iat'base portion 22 that serves as an' eye for receiving screws23 Whereliy the device is secured to the Windenr sash. From the flatbase portion 22, the wire is bent vertically in opposite directions to"a suitable distance, and then forwardly to constitute the jaws 24.lThejaws-24 are provided with eyes 25 through which the rod '3 extends,the said e'yes taking the place of the biting edges 17 oi theconstruction shown in Fig. 2. The outer-vends of the members 24 areturned toward each other and terminate in the finger-holds 26. It willthus be seen that the gripping or locking device can be constructed ofWire and obviously other forms than that shown may be employed.

I have described the principle oi operation of the in- Y vention,together with the apparatus which I now conv sider to be the bestembodiment thereof, but I desire to have it understood that theapparatus shown is merely illustrative, and that various changes may bemade, when desired, as are Within the scope of the invention.

What is claimed isz l. In a sash lock, the combination with a rodadapted to be attached to one of the parts having suitable securingmeans at one end and having a locking portion, and a guide for the upperor Afree end of said rod having a rod receiving portion slidahlelongitudinally ot' the rod to permit the guiding bracket to be securedto a suitable support atditerent distances from the attaching end of therod and serving :is an adjustable stop, of a locking device adapted tobe secured to the other part of the window and having a clamping portionadapted to coperate with said rod .and adapted to coiperate with theadjustable guide to limit the opening movement of the sash to differentheights..

2. ln a lock of th e character described, the combination with a lockingrod. of a clamping device adapted to coperate therewith composed of asingle piece of wire having an intermediate portion formedinto a loopadapted to reeeive' securing screws at opposite ends thereof, the endsoi' the wire being bent forwardly substantially at right angles to theplane of the securing loop and having convolntons forming clampingportionsadapted to coiiperate with the said rod.

ln a lock of the character described, the combination I with a rodadapted to be secured to one part, of a coperating clamping deviceadapted to be secured lo the other part comp sed it' a single piece ot'wire havingr an intermediate portion nent to form a loop adapted toreceive securing screws at opposite ends, the wire being thence crossedAand extended in opposite directions parallel to the plane of the loop,thence. bent forwardly at an angle to the plane of the loop `to form'oppositely arranged clamping,r arms; the latter hlaving eonvolutonsformed therein to receive and coperate with the locking rod` the forwardextensions of said arms serving,r as operating portions.
